Were Our Ancestors More Like Gorillas Than Humans? New Study Reveals Shocking Size Gap

Fossils reveal extreme sexual dimorphism in early hominins. The findings reshape views of their social behavior. A recent study has revealed that males of some of humanity’s earliest ancestors were much larger than their female counterparts. This marked difference in body size, found in both Aust

Sexual dimorphism — it’s scary

This is a female Latrodectus mactans. This is a male Latrodectus mactans. I brought them together this morning. The female is plump and mature. The male has large, engorged palps. This is what they…

Sharks violate Rensch's rule for sexual size dimorphism

Abstract. Systematic trends in body size variation exist in a multitude of vertebrate radiations, however their underlying ecological and evolutionary caus

OUP Academic

Sexually dimorphic traits are wide spread among mammals and emerge during development through sex-specific gene expression programs. We know very little about these programs, including the genes, regulatory networks,and cell types that underlie them. It is also unclear when differences between the sexes emerge during organ development and howsex differences evolve across species.

How giants became dwarfs: Exploring size difference in sexual dimorphism

Difference in body size (or sexual dimorphism) between males and females is common across the animal kingdom. One of the most extreme examples of sexual dimorphism is found in the cichlid fish species Lamprologous callipterus from Lake Tanganyika in East Africa, where males are 12 times bigger (heavier) than females.
